Keep your chest up/push it out more before you start pulling and keep it like that throughout the entire lift. Your hips are coming up during first pull and causing the bar to drift out/away from you. This is harder to control in a full squat than a power snatch. Maybe try some pulls from floor to knee focused on control/technique. Crack first pull then move on to second, third. OHS is pretty pointless for most people, most of the time IMO (unless narrow grip for mobility etc); better off with snatch balance.
